At STEAG GmbH\u2019s long-established power plant site in Herne\/Germany, construction is currently in progress on a state-of-the-art combined cycle gas turbine (CCGT) power plant, which is to replace the hard coal fired unit previously operated there in the course of the coming year (Figure 1). The new Herne CCGT plant, which STEAG GmbH, Essen\/Germany, is to operate together with its partner Siemens, ranks among the most flexible, efficient and consequently resource conserving power plants of its kind worldwide. STEAG has registered the coal fired unit, which went online in 1989, for final decommissioning. The aim is to convert the unit to one with a boiler fired by natural gas. It is to be used in future to back up the district heating supply at the heart of the Ruhr area.<\/p>\n
When the new Herne CCGT plant goes into continuous commercial operation in 2022, the old coal fired combined heat and power unit at the same site will be history. \u201cWith the CCGT plant, which also generates electricity and heat at the same time in accordance with the principle of cogeneration, we are ensuring a secure supply and supporting the energy system in a much more environmentally friendly way,\u201d says Ralf Schiele, who, as a member of the management board of STEAG, is responsible for Markets and Technology. And furthermore, \u201cSTEAG is building the energy future in Herne and in doing so making an important contribution to decarbonization and the success of the energy transition in the region, because the switch to natural gas will roughly halve CO2<\/sub>\u00a0emissions.\u201d<\/p>\n STEAG is also concurrently planning the second step in sustainable CO2<\/sub>\u00a0savings at the Herne site. \u201cWe will also convert the plants that are to be used to back up the heat supply in the future to lower emission fuel,\u201d says Schiele. To this end, STEAG is planning to convert the existing Herne 4 coal fired unit to a natural gas-fired boiler.<\/p>\n Performance of the necessary work within the current schedule for the construction and commissioning of the Herne CCGT plant is dependent on a permit from the transmission system operator Amprion for the final decommissioning of the former hard coal unit. \u201cSince such a decision is preceded by extensive reviews of, among other things, the system relevance of the plant to be decommissioned, STEAG has today submitted a corresponding application to Amprion in order to be prospectively ready to take action next spring,\u201d Schiele explains.<\/p>\n As soon as the transmission system operator has given its approval for final decommissioning, STEAG will be able to start implementing the plans after the 2021 heating period, i.\u2009e. in spring 2022. \u201cWith the Herne CCGT plant and the conversion of Herne 4 to natural gas, the heating supply to around 275,000 households in the heart of the Ruhr region, which is already climate-friendly today, will once again be noticeably lower in emissions,\u201d says Michael Straus, managing director of STEAG Fernw\u00e4rme GmbH.<\/p>\n In terms of resource efficiency and climate protection, it will also be possible to reduce CO2<\/sub>\u00a0emissions at the Herne site even further in the future by switching partially to green hydrogen firing.<\/p>\n STEAG\u2019s plans to convert the old coal fired unit in Herne are also good news for the Ruhr region as a business location. This is because the number of jobs that will be retained at the site in the long term even after the switch from hard coal to natural gas will be even greater. \u201cHerne is and will remain a highly skilled energy hub where the energy transition for Germany is shaped. This is good news in terms of environmental protection in our city and in the region as a whole,\u201d says Herne\u2019s Mayor Frank Dudda.<\/p>\n At the same time, the projects in Herne are an expression and symbol of the consistently pursued process of transformation at STEAG as a whole: \u201cFor several years now, we have been successfully and with increasing speed aligning the company to the growth markets of the energy future,\u201d says Joachim Rumstadt, Chairman of STEAG\u2019s Board of Management, placing the environmentally friendly conversion works at the Herne site in a broader context. \u201cNo matter whether in the field of the hydrogen economy, power generation and supply from renewables, storage technology, heat supply, the planning and implementation of customized decarbonization and efficiency solutions for industrial customers, or in the construction and operation of distributed generation plants or large-scale power plants as in Herne, STEAG always brings to the table expertise in energy that has grown over more than eight decades,\u201d says Rumstadt. This makes STEAG an active and successful contributor to the energy transition, especially in Germany.<\/p>\n \u201cBecause,\u201d as Joachim Rumstadt sums up, \u201cthe projects in Herne in particular fulfill the requirements for a forward-looking energy supply almost ideally: they guarantee security of supply, are cost-effective, resource-efficient and therefore environmentally compatible.\u201d (STEAG\/Si.)<\/p>\n","protected":false},"excerpt":{"rendered":" At STEAG GmbH\u2019s long-established power plant site in Herne\/Germany, construction is currently in progress on a state-of-the-art combined cycle gas turbine (CCGT) power plant, which is to replace the hard …<\/p>\n","protected":false},"author":25,"featured_media":12277,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[827],"tags":[75,782],"class_list":["post-12299","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-in-brief-issue-03_2021","tag-steag","tag-steag-fernwarme-gmbh"],"yoast_head":"\n
